Please no jokes, but this has been driving me crazy - did anyone else see the naked man, running fairly fast, down Fore St on Sunday, around lunchtime?

I was sat in the window seat in Il Vino's Deli and my friend and I both saw a completely naked man, run past on the other side, past the Corn Exchange - no one was with him, no one filming him, laughing at him, egging him on - nothing. He was barefoot, no bruises, cuts etc. Everyone who saw was completely baffled - but he didn't bat an eyelid, just sprinted on...
